projects beyond the sleeve and such projecting portion 18, polygonalformation, although the particular shape is optional With themanufacturer.

As will be observed from the drawing, 'the eccentric head 17 is solocated asto extend diagonally across and lie upon each side of theupper edge 19 ofthe rail base and when the device is initiallypositioned, as in Fig. 1, the low portion oi the eccentric head istoward such edge and there .is a slight cleaance between the head andtheedge ot' the rail base. This clearance should be sufficient to allow forthe variations in the size of similar rail. bases, and enable the deviceto be readily and easily positioned upon bases varying somewhat in size.

In initially positioning the device the movable gripping jaw l5 is notin place and the body of the anchor is slil'ped into position about therail base in an obvious manner. The movable gripping jaw is then placedin position as in Fig. 1. and the stem 1G is turned by means of anysuitable tool, this turns the eccentric head and brings it into agripping engagement with the edge il) of the rail base in Fig. 2. Thenthis has been done said head can be struck a sharp blow at a pointopposite from the point ot' engagement between the head and edge 1S) andthus drive the head securely into engagrement with the said edge.

As heretofore stated, the head is positioned at an angle to the lloor olthe body of the ancho and at an angle to the edge 1l) of the rail base.Owing to such angular 'disposition the pressure exerted by the iorcingof the movable gripping jaw into position will be in the direction ofthe arrow in Fig. 1. A strain in this direction will tend to force thebody of the anchor toward the bottom face of the rail base and at thesame time force it across and transversely of the bottom face of therail base, the latter movement bringing the fixed gripping ja w l) intotight engagement with that edge ot the rail against which it abuts,therefore by tightening the movable gripping jaw into engagement withthe upper edge 19 of the rail. base, an engagement will be brought aboutbetween the lower face ot' the rail base and the floor of the anchor aswell as between the fixed gripping jaw and that portion ol' the railbase against which it abuts.

lt will be observed that both the ixed straight, the tie abutmentresting squarely against the side of the tie and the ixed grippin' jawextending parallel and engaging for its full length with the edge oi'the rail base. With this construction a turning or canting movement ofthe anchor not permitted. Therefore, after the anchor is once positionedit is not intended that it shall be turned or twisted from such posiitdesired, may be of av .with the socket, thus securely grippingv jaw andthe tie abutment are tion. lt will be remembered, however, that the head17 is eccentric, therefore, after the l parts are positioned if there issullicient liorce exerted to cause. the rail to slide through the anchorsuch movement ot' the rail will turn or revolve the eccentric lie-aldto. bring it into tighter engagemeifit with the edge 1t) ol' the railbase thus drawing the lloor and the lixed .inw l) into tighter en-,uagenient with the rail and thus the anchor isautoimitically given atighter hold upon the rail as the creeping strains increase` rl`hisl'eaturc ol' the invention will, it is thought. be llearly understood byreferring to l'ig'. 5 ol" the drawings in which the directionol'moiement oi' the rail is-indirated bv the arrow.

l deem it advisable to make the head 1T of a harder metal than the metalof the rail whereby when the head is driven into place it may embed inlothe edge 19 of the rail. While lthis feature of the device is altogetherp1 amical it is not essential to the efficient operationv of the anchor,and mary be employed or not according to the judgment of the man iiiiacturer. l

ln Fig. 2 there is illustrated a slight modification ot' the 'form shownin the remaining figures of the drawine'. In this modification the steml() is tapered. and the wallsl of the bore of the sleeve 14.- aretapered in eoniorniity thereto. ln this foi-in, owing to the taper ofthe stein and the taper of 'the socket :in which. the stem-seats, alocking of the stem in place can be brought about b a blow struck on theend of the head which forces the stem into wedging engagement and tirmlycombining all oi the parts together at the initial installation ci thedevice. is stated, the tie abutment re f-rpiarely against the tie andthe fixed gripping jaw extends par-- allel, and in contact 'for itsentire length with the edge ol" the rail 'base against which it abuisand with the movable locking jaw locked in position by driving it intowedging engagement with the walls of 'the socket ll'icancl'ior is lockedin a manner to eliicientljvf prevent creeping. 'lor it any strainsshould come upon the rail lending to make it creep the tendency ':i suchi-traius would be to cause the anchor to turn but such turning isimpossible owing Ato tlvI arrangement of the tie abutment and lixedgripping jaw, and thus this strain will be inmediately resisted and thecreeping cheeked.

The a rra agement oi' the parts is such as to eliminate a movement ofthe rail through the anchor unless a breakage of the anchor shouldoccur. lt will be. noted that although the head is anggjularly disposed,nevertheless. forms and constitutes a rail engaging surface whichcontacts with the rail base at an opposed point from the fixed grippingjaw. There are thus provided jaws which nie License are oppositelydisposed from one another as 1s necessaryl and essential in anchors ofthis type and at the same time one of the ]aWs is so arranged as toexert a pressure tendingA to -pull the anchor toward and across thelower face of the rail base making substantial Contact between the railand the anchor.
